Description

Technical Field

[0001] The present invention relates to the technical field of integrated design of a control panel and a lock platform for a jacket water injection system, and in particular to an integrated design structure of a reusable jacket water injection system control panel and a lock platform. Background Art

[0002] With the accelerated development of the domestic offshore oil and gas industry, the standardized design of offshore oil and gas platforms is gradually entering a fast lane, and design standardization will become a trend. For jackets in deeper waters of China, horizontal construction is typically used, with skidding launching and floating crane-assisted righting. Jacket righting is achieved through the cooperation of a floating crane and the jacket ballast system, which coordinate to achieve a vertical transition from horizontal to vertical.

[0003] Floating crane-assisted jacket righting requires pre-installation of rigging on the jacket before it goes out to sea. A rigging platform is designed on the jacket's surfaced side to secure the rigging and facilitate personnel operations during offshore construction. The ballast system includes injection valves for injecting water into the jacket legs and a hydraulic control system to control their opening. Furthermore, a vent valve assembly and a hydraulic control system to exhaust air from the legs are included. The injection valves are typically located in holes in the submerged jacket legs and are installed nearby. The valves are hydraulically controlled, and the hydraulic control lines ascend along the jacket legs to the top of the jacket. A separate water injection system control panel is located atop the jacket, typically including a vent valve assembly and an injection valve control manifold.

[0004] However, this conventional construction scheme has many shortcomings: Low degree of standardized design: Each project requires a rigging platform and a water injection system control panel, but both need to be designed separately. The low degree of standardization goes against the current trend of standardized design.

[0005] The dismantling work is heavy: After the jacket is installed offshore, the rigging platform will be dismantled using a quick-release structure with the help of a floating crane. The water injection system control panel also needs to be cut and removed separately. This requires diving operations and a large amount of cutting work, which is highly dangerous and labor-intensive.

[0006] Non-reusable: The size of the rigging platform for different projects will vary according to the supporting structure. The water injection system control panel will often be damaged to varying degrees after cutting, and is not suitable for reuse.

[0007] Poor economic efficiency: The non-reusable nature of the product results in a huge waste of materials and pipe fittings, resulting in poor economic efficiency. Summary of the Invention

[0008] The main purpose of the present invention is to provide a reusable jacket water injection system control panel and lock platform integrated design structure to solve the problems of low standardization design, large dismantling workload, non-reusability and poor economy proposed in the related art.

[0009] To achieve the above objectives, according to one aspect of the present invention, a reusable jacket water injection system control panel and lock platform integrated design structure is provided, comprising the following steps: Step 1: Integrated design of rigging platform and water injection system control panel; Step 2: Use the rigging platform quick-release structure to connect the rigging platform to the conductor frame; Step 3: When the position of the rigging platform on the jacket needs to be changed, open the rigging platform quick-release structure and remove the rigging platform from the jacket; Step 4: Move the rigging platform to the new position of the jacket; Step 5: Use the rigging platform quick-release structure to fix the rigging platform to the new position of the jacket; Step 6: After use, open the rigging platform quick-release structure and remove the rigging platform from the conductor frame for next use.

[0010] Furthermore, the water injection system control panel adopts a standardized design.

[0011] Furthermore, the rigging platform adopts a standardized design.

[0012] Furthermore, the water injection system control panel is welded and fixed on the rigging platform.

[0013] Furthermore, the water injection system control panel includes a plurality of water injection valve control panel hydraulic interfaces, a plurality of vent valves and a plurality of vent valve control panel hydraulic interfaces.

[0015] Furthermore, the vent valves are all fixedly connected to the water injection system control panel.

[0018] Furthermore, the conductor frame and the rigging platform are fixedly connected via a rigging platform quick-release structure.

[0019] Compared with the prior art, the present invention has the following beneficial effects: the locking platform and the water injection system control panel are integrated in design, and the water injection system and the locking platform are welded and fixed without being welded to the conductor frame structure; the rigging platform is standardized in design, and the position of the connection structure between the rigging platform and the conductor frame can be changed to adapt to most conductor frame sizes for different structural sizes; the water injection system control panel is standardized in design, and the number of vent valves and the number of water injection system control panels included can adapt to the design requirements of most conductor frames; after the hydraulic control pipeline is removed, the locking platform and the water injection system control panel can be removed at one time through a quick-disassembly structure, and the dismantling work is small, the risk is low, it can be reused, and the economic value is high.
